Question

Considere as matrizes A = 4 7 2
5 3 0
2 1 2


e B = 5 0 2
4 0 1
1 3 1 Calcule at + bt

Answer 1

A =

(4 7 2)
(5 3 0)
(2 1 2)

B =

(5 0 2)
(4 0 1)
(1 3 1)

Então A transposta + B transposta é?


A transposta =

(4 5 2)
(7 3 1)
(2 0 2)

B transposta =

(5 4 1)
(0 0 3)
(2 1 1)

A transposta + B transposta =

(4 5 2) + (5 4 1) = (9 9 3)
(7 3 1) (0 0 3) (7 3 4)
(2 0 2) (2 1 1) (4 1 3)
